WINDOW-FRAME.'

Specification of Letters Iyatent.y y n yPatented,N OV, 10, 1914,

Application med october 2A, 191s. serial No. 797,051.

vshown in Letters Patent No. 1,068,149, of

July 22, 1913; and the object of the improvement is to provide a simpleand strong window frame construction which has an adjustment strip forquick close fitting the resilient stops to the sash, which strip alsocovers the opening into the sash box, thereby presenting` a continuoussmooth surface for the edge of the window sash; and the inventionconsists in the kcombination and arrangement of the parts as shown inthe specification and the accompanying drawings and pointed out in theclaims.

In the drawings, Figure 1 is an elevation of the window frame with onesidein section to show the arrangement of the differ.- ent parts at line1V W in Fig. 4. Fig. 2 is a sectional View of the window casing and sashat line X X in Fig. 4. Fig. 3 is a sectional view of the window casingat line Y `Y in Fig. 1, showing an elevation of the window jamb with thewindow sash, stops and adjustment strip removed. Fig. 4 is a crosswisesectional view of the window frame and sash at line Z Z in Fig. 1.

Like numerals of reference refer to` corresponding parts in the severalviews.

The numeral 10 designates the window jamb which is largely in one piece,and to which the weight box is attached by means of the pieces 11, 12and 13 which are preferably attached to one another by means of mortiseand rabbet joints so vthat the size or shape of the opening 14 withintheweight box is fixed.

An adjustment strip 15 is provided with a lengthwise tongue and groovejoint 16 between it and the jamb piece 10. The ad justment strip 15serves a triplepurpose. It is made wider than the projection 17 be tweenthe grooves 18 and 19 for the sash stops 20 and 21 to which it isattached so that the edges of the strip 15 adjacent the sash stops 20and 21 may be easily cut away in order to fit the space between the sashstops 20 and 21 to receive the window sash thereby insuring la tightjoint. The adjusting strip 15 also covers the opening 23 to the weightbox 14 and thereby presents a smooth continuous surface for the sash 22to slide aga-inst. The opening 23 may have the piece 24 inserted thereinor not just as desired, since the adjustment strip'15 covers the entireopening 23 and is held firmly in line bythe tongueand groove joint 16.The opening 23 yis preferably made on the lines of the projection 17iand dotted lines extending through the jamb piece 10, as shown in Fig.-4. It is therefore apparent that the adjustment strip" l5 performs thetriple office. of'forming a convenient means for fitting the sash 22,also jfori'covering the opening 23, and for providing` a smoothcontinuous sliding `surface for the sashr 22.

'Ihe `sash stops 20` and 21 may be resiliently supported by the springs25 or may extend to thebottom of the lgrooves 18 and 19 withoutdeparting from my invention. A molding 26 may be provided on theouterside of the sash box piece 1l for the trim of the brick in a brick wallor the siding of a wooden frame building. The inner edge of the jambpiece 10 may have the nishing strip 27 vwith groove 2S therein for theattachmentr of the inner wood work of the window frame, or thejamb strip10 may extend up the full thickness thereof, as desired;

I claim as new- 1. In a window frame, a jamb piece having lengthwisegrooves therein, sash stops in said grooves,v` and an adjustment stripattachedk to the projection von said jamb piece between said lengthwisegrooves on said jamb piece, said adjustmentstrip being wider than saidprojection. ,j

2. In a window frame, a j amb piece having lengthwise grooves therein,sash stops in said grooves, an adjustment strip wider than theprojection between said lengthwisey grooves in said jamb piece, and alengthwise tongue and groove joint between said strip and projection.

3. In a window frame, a jamb piece having lengthwise grooves therein,sash stops` in said grooves, a weight boxattached to In testimonywhereof I have axed my signature in the presence of tWo Witnesses.
